Inadequate end-to-end Quality of Service (QoS) and resilience support still exists across the Internet as it is difficult to achieve cooperation between the Autonomous Systems (AS) that are operated independently by Internet Service Providers (ISP). The use of an Overlay Network (ON) deployed on top of the Internet is viewed as one of the effective strategies to provide some measure of service ...

This deliverable summarizes our recent research results on the topic of service overlay networks, an innovative concept for end-to-end QoS assurance. It reports the research contributions we have achieved during the last period, including i) a technical overview and evaluations of existing architectures for end-to-end QoS with special focus on the overlay network solution, ii) our scientific co...

Peer-to-peer overlays constitute a new approach for delivering wide-area network and application services. The systems typically use a combination of self-organisation and cooperation with other peers to determine the peer’s role and performance in the overlay. Few overlays support external management mechanisms, which are the basis for overlay operators to provide specified service levels. We ...

A P2P system based on super-peer overlay shows good features of combining both advantages of hybrid and pure P2P systems. Most P2P applications being developed are based on the overlay networks composed of super-peers. Super-peer is a special peer acting as a server to a cluster of client peers. Selecting super-peers and constructing a super-peer overlay for clustering client peers are importan...

REsource LOcation And Discovery (RELOAD) is a peer-to-peer signaling protocol that can be used to maintain an overlay network, and to store data in and retrieve data from the overlay. RELOAD is currently being standardized in the Internet Engineering Task Force (IETF). The main application using RELOAD is Peer-to-Peer Session Initiation Protocol (P2PSIP). In this paper, we study the performance...

Different industrial decision makers and managers in our country, try to select and organize locations for aggregating industrial units, estates and areas with respect to land use planning visions and industrial development strategies. In this regard, considering large quantity of the input data and diverse criteria affecting this application, it is complicated and difficult to optimally make d...

Many cooperative overlay multicast systems of diverse designs have been implemented and deployed. In this paper, we explore a new architecture for overlay multicast: we factor out the control plane into a separate overlay that provides a single primitive: a configurable anycast for peer selection. This separation of control and data overlays has several advantages. Data overlays can be optimize...

Developing peer-to-peer systems is a big challenge, because they typically operate in large-scale, highly unreliable and insecure environments and involve the collaboration of many nodes (i.e. computers) in the network. In recent times, a lot of efforts have been devoted to the system design of peer-to-peer systems, resulting in new structured overlay networks. These overlay networks perform th...

Overlay networks are networks operating on the inter-domain level, where the edge hosts learn of each other and, based on knowledge of underlying network performance, they form loosely coupled neighboring relationships. These relationships can be used to induce a specific graph, where nodes are representing hosts and edges are representing neighboring relationships. Graph abstraction and the as...

In recent years, Internet has known an unprecedented growth, which, in turn, has lead to an increased demand for real-time and multimedia applications that have high Quality-of-Service (QoS) demands. This evolution lead to difficult challenges for the Internet Service Providers (ISPs) to provide good QoS for their clients as well as for the ability to provide differentiated service subscription...
